Its a DnD game Stabbey, i think beeing able to make your own character is one of the most basic assumptions one can make when it comes to such a game
Yes, it's a DnD game.
However, it is also a videogame. I'm sure Larian will try their best to do interesting things for custom characters, but a custom character you create in a videogame will never, ever have the personal attention to detail and the depth of story interactions that you can get with a human dungeon master that tailors a plot based on a player's character in a pen and paper RPG.
When BG 3 comes out, I'm sure that I can make a Halfling Wizard in the game. Will I be able to make the story of Wilbur Greenmeadow, who left his home and life as a gardener behind in an effort to prove himself just as worthy and as great a hero as Melvin Swiftcurrent, who retired back to Blueberry Hills Shire after a series of exciting adventures? Will I be able to fulfill Wilbur's objective to find his missing master, the Wizard who took him in and trained him as an apprentice only to vanish suddenly when Wilbur was running errands in town, leaving behind an abandoned and searched tower? I probably won't be able to do that.
All the input I can give to the game will be race, class, a background and maybe some granularity to the background (Wilbur will have the [Sage] background, with the subtype [Wizard's Apprentice]. And I don't even know if they'll implement the background subtype.) If Larian is really, REALLY ambitious, they might even allow you to select from a short list of "Bond","Ideal", Flaw". But I cannot and do not expect the game to be able to take into account the sort of specific backstory that you can have in a pen and paper RPG.
